Corrosion protection when storing car body shells

Dehumidification: dry air protects metal parts

In 2012, the average humidity in Europe amounted to 73 % – depending on the weather. The storage of metal car parts in the automotive industry, however, requires drier air with a maximum humidity level of 40-50 %, in order to avoid corrosion. This can reliably be achieved by use of our industrial devices for dehumidification and additional heaters. 

Checking the humidity values with respect to corrosion protection is one of the chief climate conditioning tasks in the automotive industry. In addition to process air conditioning during all stages of the production chain, dehumidification plays a key role in all storage facilities. Particularly well suited for the dehumidification in body shell or component storehouses are the high-performance devices of the TTR series. These desiccant dehumidifiers are available in several mobile and stationary designs – our climate experts from the industrial services team will gladly assist you in finding out which version is ideal for your body shell storehouse.

Dehumidification and additional heating in storage spaces

If body shell storehouses are additionally to be heated during the cold period, we recommend mobile heating devices from the Trotec range of products. Since warm air absorbs more humidity, though, we only recommend the use of additional heaters, if humidity has been reduced beforehand. Room temperature and humidity constitute a sensitive combination and have to be precisely measured and controlled in order to provide reliable corrosion protection for storage facilities. For this purpose we have numerous measuring devices on offer, e.g. the thermogygrometers T210 and T260. The latter can also be used as laser pyrometer and dew point alarm signal generator. Furthermore, the data loggers of the MultiMeasure Professional series, DL200H or DL200X, manufactured in Germany, provide manifold possibilities for tamper-proof long-term measurements.

Drafting and test run: make use of our industrial services

For industrial customers the Trotec Group not only offers devices, but solutions. We draft the climate conditioning for your storage spaces and test it beforehand in trial operation using mobile devices. No matter whether temporary or stationary: Only after measurements have proved that humidity and storage temperature can be controlled as desired will your final solution for corrosion protection in storage facilities be launched.

Make use of Trotec's best practice industrial services

Since every industrial undertaking has characteristic process flows, installations and facilities, every air treatment solution demands case-specific device configurations. All in all, the combined effects of air currents, humidity conditions and temperature fluctuations are often hard to calculate on a purely theoretical basis, e.g. in airlock areas or on conveying paths. The consequence: Unnecessary additional costs due to an overestimated demand or – even worse – solutions not working sufficiently in real life.

You can count on our experts

In order to precisely calculate the demand in the industry and to develop tailor-made concepts for climate conditioning experienced climate specialists are needed. Rely on our team of experts as well as the industrial services: We analyse the individual requirement situation with you present on site, determine the specific demand for devices and develop a tailor-made project solution right up to the exact positioning of the devices.

Before the planned stationary units are installed, our service team first works with mobile versions of the drying units as part of a trial run. These can be put up without any difficulty or the need for structural changes.

During this validation phase we document all relevant climate parameters such as air temperature, relative humidity, dew point or flow rate for a final optimization of the requirement calculation.

Trotec is the only provider of this advantage:

Thanks to the unique option of non-binding trial operation you will invest solely in solutions which have verifiably proven their worth in everyday operation meeting your individual on-site requirements. The stationary units will not be ordered until you are fully satisfied with our concept. The only costs incurred consist of an inexpensive hiring flat rate for the time of test operation.

Just give us a call at +49 2452 962-777 – our industry consultants will be pleased to help you personally and provide information regarding our best practice industrial services. Or send a request indicating your personal requirements directly to our industry experts. We will answer promptly!

Upon request, we also produce customized desiccant dehumidifiers as special models

Upon request, we will readily produce tailor-made desiccant dehumidifiers as special models “made in Germany” perfectly geared to your needs, e.g.:

  • TTR industrial desiccant dehumidifiers with hygienic design
  • TTR industrial desiccant dehumidifiers for PWIS-free dry air
  • TTR industrial desiccant dehumidifiers with extremely low dew point

Makes use of the possibility of having special models with tailored components for your individual needs planned, designed and manufactured in close consultation with our specialists.
